No X11 DISPLAY variable was set, but this program performed an operation which requires it.

I am using the ibmi plugin to check many iseries. Over the weekend I started getting the below error. We are using a centos 7 server to run the plugin. Other iseries work ok, its just one that is not working, very strange.

Here is my command: ./check_ibmi_status.sh -M ASPUsage -SSL n -H $ARG6$ -W 90 -C 95

I have tried setthing the DISPLAY variable, but that does not fix the issue.

Any ideas?

I had a strange behaviour like yours, once. Solved by creating a fresh new user profile, copying untouched QSECOFR and then, after testing, restricting rights/class.

Try setting environment variable JAVA_TOOL_OPTIONS=-Djava.awt.headless=true
